摘要： Mechanisms for generating checkpoints in a speculative versioning cache of a data processing system are provided. The mechanisms execute code within the data processing system, wherein the code accesses cache lines in the speculative versioning cache. The mechanisms further determine whether a first condition occurs indicating a need to generate a checkpoint in the speculative versioning cache. The checkpoint is a speculative cache line which is made non-speculative in response to a second condition occurring that requires a roll-back of changes to a cache line corresponding to the speculative cache line. The mechanisms also generate the checkpoint in the speculative versioning cache in response to a determination that the first condition has occurred.

摘要： Mechanisms are provided for inserting indicated instructions for tracking and indicating exceptions in the execution of vectorized code. A portion of first code is received for compilation. The portion of first code is analyzed to identify non-speculative instructions performing designated non-speculative operations in the first code that are candidates for replacement by replacement operation-and-indicate instructions that perform the designated non-speculative operations and further perform an indication operation for indicating any exception conditions corresponding to special exception values present in vector register inputs to the replacement operation-and-indicate instructions. The replacement is performed and second code is generated based on the replacement of the at least one non-speculative instruction. The data processing system executing the compiled code is configured to store special exception values in vector output registers, in response to a speculative instruction generating an exception condition, without initiating exception handling.

摘要： Mechanisms are provided for tracking exceptions in the execution of vectorized code. A speculative instruction is executed on a vector element of a vector. An exception condition is detected in association with the vector element based on a result of executing the speculative instruction on the vector element. A special exception value is stored in the vector element in a vector register corresponding to the vector, indicative of the exception condition, without invoking an exception handler for the exception condition. The special exception value is propagated with the vector element of the vector through a processor architecture of the processor, without invoking the exception handler for the exception condition. An exception corresponding to the exception condition indicated by the special exception value is generated only in response to a non-speculative instruction being executed that performs a non-speculative operation on the vector element.

摘要： Mechanisms for performing a scattered load operation are provided. With these mechanisms, an extended address is received in a cache memory of a processor. The extended address has a plurality of data element address portions that specify a plurality of data elements to be accessed using the single extended address. Each of the plurality of data element address portions is provided to corresponding data element selector logic units of the cache memory. Each data element selector logic unit in the cache memory selects a corresponding data element from a cache line buffer based on a corresponding data element address portion provided to the data element selector logic unit. Each data element selector logic unit outputs the corresponding data element for use by the processor.

摘要： Mechanisms for performing a complex matrix multiplication operation are provided. A vector load operation is performed to load a first vector operand of the complex matrix multiplication operation to a first target vector register. The first vector operand comprises a real and imaginary part of a first complex vector value. A complex load and splat operation is performed to load a second complex vector value of a second vector operand and replicate the second complex vector value within a second target vector register. The second complex vector value has a real and imaginary part. A cross multiply add operation is performed on elements of the first target vector register and elements of the second target vector register to generate a partial product of the complex matrix multiplication operation. The partial product is accumulated with other partial products and a resulting accumulated partial product is stored in a result vector register.
